CREATE_PR doesnt seem to be working with `on:push`

[guergana]

Describe the bug: バグの概要

The action creates a commit properly but given the flag CREATE_PR it doesn't create a PR with the ToC. This was tested when pushing to a specific folder. I don't know if the CREATE_PR flag is working when no folder is specified.

To Reproduce: 再現手順

Steps to reproduce the behavior:

1. Create a workflow that uses the CREATE_PR flag:

   
   name: Update Table of Contents (ToC)

on: push: paths:

• docs/**

jobs: generateTOC: name: TOC Generator runs-on: ubuntu-latest steps:

• uses: technote-space/toc-generator@v4 with: CREATE_PR: true TARGET_PATHS: ./docs/*.md

  
  2. Push some changes to specified folder. The workflow will run and create a commit at the end of the PR that created the changes in the folder.
  3. Check github, the create PR prompt is not triggered.

Expected behavior: 期待する動作

A PR is opened with on:push event.

The flag works with on:pull_request event.
